Title: Motor boat cooling water intakes - are connected to supply pipes uia uented settling tank below water line
IPC: B63B17/00
Filed: 1973-05-08
Abstract: The intakes are located either side of the keel which is hollow. The intakes are connected to a settling tank. The keel and settling tank will be maintained full of water whether the craft is stopped or travelling ahead or astern. The settling tank is vented, and has any number of suction-pipes as required in it to feed the necessary cooling circuits. Each circuit includes a pump, filter and valves. This method of collecting cooling water eliminates the need for a pump before the settling tank which is below the waterline. The reduced drag due to the reduced number of water inlets ensures adequate suction to the various circuits.

Title: Extending oven or grill shelf - fixed outer wire frame carries rollers for sliding inner wire frame
IPC: F24C15/16
Filed: 1974-04-02
Abstract: The food shelf for an oven or grill, is in the form of a wire frame with a rectangular part (2) wide enough to be retained between side walls (5) of the oven or casing, with a pair of longitudinal wires (6) spaced apart vertically so as to form a track for a pair of rollers (3). On a cross wire (2) is mounted a further pair of rollers (4). Over these four rollers is supported a narrower rectangular frame (1) which can thus be extended, travelling on the rollers. Inverted L-shaped side clips (7) attached to the outer frame prevent the inner one from lifting. End stops (9) on the inner frame limit its travel, and vertical rods (10) support the carrier for the food.
Patent FR-2271414-A1 (FR)
Title: Rotary water powered generator wheel - has peripheral caissons with pistons moving air to central collector
IPC: F03B17/02
Filed: 1974-05-17
Abstract: The wheel may drive alternators and has a hub mounted air collector (8) and peripheral caissons (5). The latter are arranged in diametrically opposed pairs and each comprises an internal chamber whose central axis is in the vertical plane containing the wheel and tangential to the wheel. Inside each chamber is a sliding piston (4) which forms an open chamber and an air collector by radial conduits (7). When a pair of caissons are at the ends of a vertical dimater of the wheel the associated pistons slide in opposed directions due to gravity such that the lower caisson fills with water and joins air towards the collector as the wheel turns and the upper caisson fills with air, the resulting weight difference over the wheel tending to turn the wheel.

Title: Oil recovery with micellar dispersions contg. sulphonates - prepd. from gas oil contg. oxygenated hydrocarbons
Inventor: JONES STANLEY CULVER
IPC: C09K8/584
Filed: 1975-02-04
Abstract: In the recovery of oil from subterranean oil-bearing formations by injection of a micellar dispersion consisting of hydrocarbons, a petroleum sulphonate and an aq. medium, the petroleum sulphonate is prepd. by sulphonating a gas oil contg. 1-50 (pref. 3-35) wt% of oxygenated hydrocarbons. It is not necessary to extract the petroleum sulphonate from the sulphonation mixt., thus avoiding laborious and costly solvent extraction. The sulphonates obtd. give better oil recovery yields than those obtd. without the use of oxygenated hydrocarbons.
Patent FR-2262558-A1 (FR)
Title: Bottle hanger for resin spraying machine - has perforated cup kept clean by circulating air jet
IPC: B05B15/04
Filed: 1975-02-28
Abstract: A suspension system for bottles in continuous resin coating machines which makes them unbreakable uses hangers on an endless conveyor system, each with a cup-shaped cover and a bottle grip. The top periphery of the cover has a number of holes so that a jet of gas can be blown through the holes inside the cup. This reliably prevents any of the resin coating applied by the external spray guns from entering the inside of the hangers. The hangers are simple in design and cheap to make.
